How to reset the alarm on 2003 honda odyssey

I was away for the weekend and my factory installed audible alarm went off for no apparent reason. I was inside my mother in laws house and hit the unlock button on my remote- took me about 2 minutes to get it-the alarm stopped and I hit the lock button on remote- lights flashed letting me know it was locked.
I left later in the day and drove home - about 1.5 hr drive-when I got home my remote would not lock the vehicle- I had to use my other remote-it locks and unlocks vehicle but the alarm no longer sets.
I thought it might be a problem with the first remote battery so I started to change it- I was inside the house and the alarm went off - on the drive way.
The first remote still does not work even after trying to reset it as per directions on other feeds- key in - position II - push "lock" button - repeat 3 times- locks cycle to program mode-
So, I have one remote that won't unlock or lock the vehicle, but it will start it and I can drive without issue.
I have another remote which will lock and unlock the vehicle and start the car.
But... I seem to have NO audible alarm.
I have heard about a "valet/reset" button or switch but cannot locate it under the dash.
Have also heard about fuse # 13 for passenger door & alarm reset but have not tried that one yet.
Can you help at all or am I stuck going to pay a Honda tech to fix what should be a simple problem??
Thanks in advance.

sounds like the drivers side key switch has failed remove the interior door panel and there will be a switch attached to the back of the key lock cylinder or around there it should be two or three wires also check the door jamb wire harness where the door closes for any broken or damaged wires, use a vot meter and see if you get power or ground to the opposite side of the switch when you use the key to lock and unlock the door if nothing changes and there is power or ground! at this switch i would replace it, i don't think there is one but if the car has a passenger side key hole try to unlock the car from that side and see if you get the same problem -jeff

How do I disable my factory alarm on my 2003 Honda Odyssey

Easiest way to go about it is to locate and disconnect the sound producing element of system. If alarm also kills the ignition then it is not so easy.

Where is the reset button located in a 2003 Honda Odyssey for the anti theft?

If the remote was programmed before loss of power, push and hold the unlock button until the alarm stops. If not try locking and unlocking the drivers side door with the the key. This has reset the alarm on my 2001 Odyssey.

You will also need the unlock code to reactivate your stereo after long term power loss. It is on a card with the manual given to the owner of new vehicles. A smart dealer will put it on a sticker in the glove box. Otherwise you have to remove the radio and give a Honda dealer the radio serial number to get the unlock code. Don't try it randomly; 10 incorrect tries locks the stereo.

Reset factory alarm

There IS a reason it comes on. It isn't there for looks, it serves a purpose. Verify you have the right amount of oil. Make sure when the oil is changed it is the right viscosity and weight recommended by Honda (probably a 5W-30). When it's cold, the oil is thicker and harder to pump. So typically people in colder climates should run a lower weight oil in the winter (probably 5W30 in the winter, and 10W30 in the summer)

Honda Odyssey 2004 no alarms

There is most likely a reset button under the dash somewhere. You can try pressing and holding that button down while pressing the lock button on the remote. If this does not work simply have the dealer reset it for you.
